Systems, methods, and instrumentalities to select a distributed gateway (D-GW). A WTRU may be configured to detect a request for an address associated with content. The WTRU may receive an address list associated with the content. The WTRU may select a distributed gateway (D-GW). If an address of a currently connected D-GW is included in the address list, the WTRU may select the currently connected D-GW. If the address of the currently connected D-GW is not in the address list and an address of an anchor D-GW that is not currently connected is included in the address list, the WTRU may select the anchor D-GW that is not currently connected. If the address of the currently connected D-GW is not in the address list and the address of the anchor D-GW that is not currently connected is not in the address list, the WTRU may select the currently connected D-GW.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A wireless transmit/receive unit (WTRU) comprising: a memory; and a processor, wherein the memory comprises instructions that when executed cause the processor to: detect a request for an address associated with content; receive an address list associated with the content; and select a distributed gateway (D-GW), wherein: if an address of a currently connected D-GW is included in the address list, the currently connected D-GW is selected, and if the address of the currently connected D-GW is not in the address list and an address of an anchor D-GW that is not currently connected is included in the address list, the anchor D-GW that is not currently connected is selected, and if the address of the currently connected D-GW is not in the address list and the address of the anchor D-GW that is not currently connected is not in the address list, the currently connected D-GW is selected.
2. The WTRU of claim 1 , wherein the instructions when executed further cause the processor to send a query to a network entity requesting the address list.
3. The WTRU of claim 2 , wherein the instructions when executed further cause lire processor to send a message to the selected D-GW requesting the content.
4. The WTRU of claim 1 , wherein the instructions when executed further cause the processor to select the D-GW when the WTRU is anchored to one or more distributed gateways.
5. The WTRU of claim 1 , wherein the WTRU does not release a deprecated IP address from the address list for a holding period.
6. The WTRU of claim 2 , wherein the query is a DNS query and the network entity is a DNS server.
7. The WTRU of claim 1 , wherein the instructions comprise instructions associated with at least one of a dynamic adaptive streaming (DASH) entity or a management entity.
8. The WTRU of claim 7 , wherein the distributed gateway selection is associated with the management entity.
9. The WTRU of claim 8 , wherein the instructions when executed further cause the processor to indicate the distributed gateway selection to the DASH entity.
10. The WTRU of claim 9 , wherein the instructions when executed further cause the processor to receive an indication from the DASH entity indicating that the selected distributed gateway is to be used.
11. A method of selecting a distributed gateway (D-GW) for receiving content via a wireless transmit/receive unit (WTRU) comprising: receiving an address list associated with the content; and selecting the D-GW, wherein: if an address of a currently connected D-GW is included in the address list, the currently connected D-GW is selected, and if the address of the currently connected D-GW is not in the address list and an address of an anchor D-GW that is not currently connected is included in the address list, the anchor D-GW that is not currently connected is selected, and if the address of the currently connected D-GW is not in the address list and the address of the anchor D-GW that is not currently connected is not in the address list, the currently connected D-GW is selected.
12. The method of claim 11 , further comprising sending a query to a network entity requesting the address list.
13. The method of claim 11 , further comprising sending a message to tire selected D-GW requesting the content.
14. The method of claim 11 , further comprising selecting the when the WTRU is anchored to one or more distributed gateways.
15. The method of claim 11 , wherein the WTRU does not release a deprecated IP address from the address list for a holding period.
16. The method of claim 12 , wherein the query is a DNS query and the network entity is a DNS server.
17. The method of claim 11 , wherein the WTRU comprises at least one of a dynamic adaptive streaming (DASH) entity or a management entity.
18. The method of claim 17 , wherein the distributed gateway selection is associated with the management entity.
19. The method of claim 18 , further comprising indicating the distributed gateway selection to the DASH entity.
20. The method of claim 19 , further comprising receiving an indication from the DASH entity indicating that the selected distributed gateway is to be used.
